How to design channel select VI for Agilent34970A

Question

Hello Guys,
             I want to design a temperature data acquisition system by using 34970A,but now i have a problem that i don't know how to design a channels selecting vi?
My idea is to select any channel from multiple channels to scan,pls help me for explaining how to do,because my labviw knowledge and experience  is so poor.

Thanks for the response.  In order to incorporate the sampling information (sampling frequency) into my data ( 160 X 512 2-D Array), I use "Build Waveform.vi." However, for the input argument "Y," I can only use a 1-D array.  I try with my 2-D array, but it gives me a connection error.  So, my first thought was to stick the Build Waveform.vi into a for loop with a shift register.  I use an indexing tunnel node when guiding my data array into the loop.  I then connect the 1-D array to the build waveform.vi, and send the output to a "Build Array.vi" where the output goes to the shift register, and the other input comes from the first shift register.  What prevents this from working i.e., creating a 2-D waveform array, is that the option to uncheck the "Concatenate Inputs" is not available when i right click on the  Build Array.vi.  I notice that I do have the option to uncheck it when i'm just using 2 waveforms without the shift register.  Would you have any suggestions?  I want keep it running as efficient as possible, so i figured that I might want to avoid doing the filtering 160*13 times, manually.
would there be any advantage to using the Digital IIR Filter.vi over the Butterworth Filter.vi ?  The input for the former is a waveform while for the latter is a plain ol' array, but i notice that i can send a waveform into it and i don't get an error.
